DE-LA-CAFFINIERE THUMB CARPOMETACARPAL REPLACEMENTS - 93 CASES AT 6 TO 16 YEARS FOLLOW-UP

The results of 93 de la Caffiniere thumb joint replacements in 71 pati ents were reviewed between 6 and 16 years. The survival rate was 89% a t 16 years. Eleven thumb joints had failed requiring revision, The com monest reason for failure was aseptic loosening of the trapezial compo nent. The failure rate was higher in men of working age than any other group, which possibly reflects the increased demands on the prosthesi s of these patients. We support the use of this implant for degenerati ve osteoarthritis, but caution against its use in men under 65 years.
